Detailed implementation manners

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figure 1 and Figure 2 shown, a gate opening and load gauge for water conservancy projects in an embodiment of the present utility model includes a housing 1. A terminal block 13 is installed on the rear panel of the housing 1, and electronic components are installed inside the housing 1. In actual use, since the housing 1 is used in environments with high humidity such as hydropower stations and reservoirs, moisture will enter the housing 1 from the rear panel of the housing 1, and the electronic components inside the housing 1 will be damaged after the moisture condenses into dew.

[0028] As Figure 2 and Figure 3As shown in the figure, a plastic block 2 is installed on the inner wall of the housing 1. A wire hole 21 is provided on the plastic block 2. After the wire is led out from the terminal block 13, it passes through the wire hole 21 and then is connected to the electronic components inside the housing 1. The aperture of the wire hole 21 matches the outer diameter of the wire, which can effectively prevent moisture from passing through the wire hole 21.

[0029] Preferably, after the wire passes through the wire hole 21, paraffin can be used to seal the connection between the wire hole 21 and the wire.

[0030] A through groove 11 is provided on the side wall of the housing 1 away from the plastic block 2. The through groove 11 penetrates the side wall of the housing 1. A moisture-proof component is inserted into the through groove 11. The moisture-proof component includes a sealing plate 3. The sealing plate 3 is used to separate the electronic components inside the housing 1 and the terminal block 13. Specifically, the sealing plate 3 penetrates the through groove 11 and is inserted into the housing 1. The sealing plate 3 divides the housing 1 into two independent spaces.

[0031] Furthermore, a first sliding groove 12 is provided on the housing 1, and a plugging groove 22 is provided on the plastic block 2. After the sealing plate 3 penetrates the through groove 11, it is slidably connected to the first sliding groove 12. One end of the sealing plate 3 penetrating the through groove 11 is clamped in the plugging groove 22. Specifically, the first sliding groove 12 guides the sealing plate 3. When the sealing plate 3 penetrates the through groove 11, it can slide vertically in the first sliding groove 12, and it can ensure that one end of the sealing plate 3 can be clamped in the plugging groove 22. Since the material of the plugging groove 22 is plastic and has a certain elasticity, it can make the interface between the sealing plate 3 and the plugging groove 22 in a sealed state and prevent moisture from passing through.

[0032] Furthermore, a first sealing layer 111 is covered on the through groove 11. The first sealing layer 111 can seal the connection between the sealing plate 3 and the through groove 11. A second sealing layer 121 is covered on the first sliding groove 12. The second sealing layer 121 can seal the connection between the sealing plate 3 and the first sliding groove 12. Preferably, the first sealing layer 111 and the second sealing layer 121 are made of silica gel material, which can clamp the sealing plate 3 and prevent moisture from passing through.

[0033] After the electronic components inside the housing 1 are isolated by the sealing plate 3, although it can ensure that the electronic components inside the housing 1 are not affected by moisture, the terminal block 13 exposed to the air will still rust. After the terminal block 13 rusts, the resistance increases, affecting the accuracy of the gate opening load gauge for water conservancy projects.

[0034] To protect the terminal block 13 on the housing 1, as Figures 3 to 5As shown in the figure, a first placement groove 31 is formed in the sealing plate 3, and moisture-absorbing particles are contained in the first placement groove 31. A second placement groove 32 is also formed in the sealing plate 3. The second placement groove 32 communicates with the first placement groove 31, and a cloth box 4 is snap-fitted in the second placement groove 32. A non-woven fabric 41 is adhered to the cloth box 4, and a sliding rod 42 is adhered to one end of the non-woven fabric 41 away from the cloth box 4.

[0035] Specifically, a second sliding groove 35 is formed in the groove wall of the first placement groove 31. The second sliding groove 35 communicates with the second placement groove 32. A third placement groove 36 is formed at one end of the second sliding groove 35 away from the second placement groove 32. The sliding rod 42 can slide in the third placement groove 36. When the sliding rod 42 is snap-fitted in the third placement groove 36, both ends of the non-woven fabric 41 are in the third placement groove 36. In this way, a closed placement space is formed between the non-woven fabric 41 and the bottom wall of the first placement groove 31, and moisture-absorbing particles can be contained.

[0036] It should be noted that when the moisture-absorbing particles in the placement space are used for a period of time, the moisture-absorbing particles need to be replaced. When replacing, first pull out the sealing plate 3 from the housing 1, then pull out the sliding rod 42 from the third placement groove 36, so that the third placement groove 36 slides down from the second sliding groove 35, and the moisture-absorbing particles in the placement space can be poured out. After replacing with new moisture-absorbing particles, pull up the sliding rod 42 and push it into the third placement groove 36 to fix the replaced moisture-absorbing particles in the placement space again. Finally, insert the sealing plate 3 back into the housing 1.

[0037] Furthermore, a handle groove 33 is formed in the sealing plate 3. When inserting and pulling out the sealing plate 3, the handle groove 33 can be held by hand to make it easier to exert force.

[0038] Preferably, the moisture-absorbing particles are montmorillonite desiccants, which have a fast adsorption speed, high adsorption capacity, are non-toxic and non-contact corrosive. They can adsorb the water vapor in the air around the terminal block 13, keep the air near the terminal block 13 dry, and can effectively prevent the terminal block 13 from rusting, further ensuring the use accuracy of the gate opening load gauge for water conservancy projects.

[0039] As Figure 1 、 Figure 2 and Figure 4 shown, in order to firmly insert the sealing plate 3 into the housing 1, a fixing block 5 is welded on the side wall of the housing 1. A locking pin 51 is slidably connected to the fixing block 5. A through hole 34 matching the locking pin 51 is formed in the sealing plate 3. The locking pin 51 passes through the fixing block 5 and is inserted into the through hole 34 on the sealing plate 3. An end cap 53 is integrally formed at one end of the locking pin 51 away from the sealing plate 3. A spring 52 is welded to the end cap 53, and one end of the spring 52 away from the end cap 53 is welded to the fixing block 5.

[0040] Specifically, when the sealing plate 3 is inserted into the through groove 11, the locking pin 51 is inserted into the through hole 34 on the sealing plate 3, so that the sealing plate 3 cannot be pulled out of the through groove 11, and the sealing plate 3 is firmly inserted on the housing 1.

[0041] During use, the moisture-absorbing particles are laid flat in the first placement groove 31, and then the sliding rod 42 is pulled, and the sliding rod 42 is snapped into the third placement groove 36. One hand pulls the end cover 53, and the sealing plate 3 is pushed into the through groove 11. When the sealing plate 3 cannot be pushed, the end cover 53 is released, and the end cover 53 can be inserted into the through hole 34 under the action of the elastic contraction force of the spring 52, and the sealing plate 3 can be locked.

[0042] When the moisture-absorbing particles need to be replaced, similarly, one hand pulls the end cover 53, and the other hand holds the handle groove 33 and pulls outwards, then the sealing plate 3 can be taken out of the housing 1. After taking out the sealing plate 3, the sliding rod 42 is pulled so that the sliding rod 42 enters the second sliding groove 35 from the third placement groove 36, and the sliding rod 42 is slid onto the cloth box 4, then the moisture-absorbing particles on the first placement groove 31 can be poured out to replace with new moisture-absorbing particles.
